Senate Democrats erupted en masse Tuesday after President Trump said Sen. Kirsten Gillibrand, D-N.Y., would "do anything" for campaign contributions when he was a backed Democratic candidates, a suggestion deemed "despicable" and "disgusting."

Gillibrand said the attack was a "sexist smear" against her in the wake of her call for an investigation into the allegations against the president for sexual misconduct. Her colleagues backed her up Tuesday, with some making it known they believed Trump was insinuating that Gillibrand offered sexual favors for campaign dollars.

"The tweet about Sen. Gillibrand is a sexist slur that disgraces the office and diminishes the presidency. It's utterly reprehensible," said Sen. Richard Blumenthal, D-Conn., who declined to weigh the tweet against others that Trump has fired off against political opponents in his first year in office.

"I'm going to assess only this one — directed against a sitting United States senator for her focus on issues relating to sexual harassment and assault, which implied such derogatory aspersion on her that I think it is really distinct and despicable."

Gillibrand is one of a handful of Democratic senators who believe Trump should resign due to the allegations put forth, including Sen. Cory Booker, D-N.J., and Sen. Elizabeth Warren, D-Mass.

Warren laced into Trump for the comment, saying it was an attempt at "slut-shaming" the New York Democrat. The potential 2020 candidate even went so far as to talk to the Capitol Hill press corps about the remark — a rarity given her reticence to do so normally, saying it was "clear" what the president was trying to say.

"Disgusting. It was disgusting," Warren reportedly said. "It’s clear what he was getting at.”

Sen. Mazie Hirono, D-Hawaii, echoed Warren's line, calling Trump a "sexual predator" who needs to exit the White House.

"He’s a misogynist and admitted sexual predator and a liar," Hirono said. "The only thing that will stop him from attacking us, because nobody is safe, is his resignation.”

Gillibrand herself is fundraising off the comment, sending an email to supporters Tuesday asking for donations and pledging she "won't be silenced by a tweet."

However, there are some Democrats who do not believe Trump should resign over the allegations, including those who hail from states where the president remains popular.

"He ought to put the phone away and govern. That's what he should do," said Sen. Jon Tester, D-Mont., one of the five Democratic senators up for re-election in states the president won by double digits last November. However, Tester was curt when asked about the possibility of resignation.

"Nope," he said. Others simply believe Trump's resignation is implausible, no matter how much they wish it would happen.

"I think the resignation thing is — he's not going to resign," said Sen. Tim Kaine, D-Va., who called the tweet "low-life behavior."
